The difference between wheel hub and brake drum

The nature is different: the wheel hub is the rotating part of the wheel core connected by the column of the inner profile wheel steel of the tire. The brake drum is the friction coupling of the drum brake, except that it should have the strength and rigidity required as a component.

How to choose the hub size

When you usually look at the introduction of the model, have you found a phenomenon: in addition to some differences in performance and configuration, the wheel hub size is also different between the different configurations of some models. The more expensive the configuration, the larger the wheel size, and the appearance looks more sporty and better.

What to pay attention to when the car is braking

As we all know, the braking system is often used in the driving process of the vehicle. As a car owner, you must learn to use it skillfully. So what should you pay attention to when braking? If it is driving after rain, pay attention to reduce the driving speed and lightly step on the brake pedal to avoid accidents.

Do you know the working principle of brake drums

When the brake drum is working, when the pad wears, more space will be created between the brake shoe and the drum. When the car stops during reversing, it will push the brake shoe to make it close to the drum. When the gap becomes large enough, the adjustment lever will shake enough to advance the adjustment gear by one tooth. The adjuster has a thread like a bolt, so it can be loosened a bit when turned and extended to fill the gap. Whenever the brake shoes wear a little, the adjuster will advance a little more, so it always keeps the brake shoes close to the drum.

What is the difference between the wheel hub and the brake drum

Wheel hub: Wheel hub is also called rim, tire bell, and wheel. It is a metal part that is barrel-shaped and the center is mounted on the shaft. The wheel hub is based on the length of the diameter, the width, and the difference in molding methods., Different materials used are divided into many different types.

Brake drum mechanical failure cause inspection

First, support the hot brake drum with a jack, charge the air pressure to more than 8kg, step on the brake, and then release the brake. If the brake adjustment arm of the brake drum cannot return in time, it can be judged that it is The cause of the mechanical failure; then check the return of the brake adjustment arm by pulling the handbrake and releasing the handbrake. The following factors can cause the brake adjuster arm not to return or to return slowly:

Correct understanding of brake drum

The brake drum is a fragile gray cast iron material, which is a cast iron piece similar to a hand drum. It is fixed with the tire and rotates at the same speed. When braking, the oil pressure pushes the brake shoe to contact the inner edge of the brake drum, and the friction generated by the contact inhibits the rotation of the tire to achieve the purpose of braking.

Truck brake drum 9 major intractable disease analysis, how many have you encountered?

However, at this stage, drum brakes are still the configuration of more than 90% of medium and heavy truck products in China. As one of the core components of the vehicle brake system, the brake drum is also a wear consumable. When the brake drum is worn to a certain limit, it needs to be replaced. The vast majority of brake drum replacement is due to the expiration of the life of the brake drum replacement.

What are the design requirements of the brake drum

The brake drum working surface is generally finished with the bearing hole positioning after assembly with the hub. Mini cars require roundness and coaxiality tolerances of working faces ≤ 0.03mm, radial runout ≤ 0.05mm, and static unbalance ≤ 1.5N · cm.
